Ideas for Vusion Manager

Currently we have in item JSON Structure just one possible "custom" layer. With this request I would like to ask for more layers/objects in custom section under consideration to have a better and clear structure. We are not able to define all needed values on Vusion´s provided fields on our variety of Items.

Datastructure like:

{
"custom": {
"subGroup": {
"prop1": "",
"prop2": "",
"prop3": ""
}
}
}
